Conclusion This essay provided an analytical account of the emergence and development of social welfare in the newly emerging oil-rich state of Kuwait, by delineating the particular historical conditions and socio-economic transformations which were responsible for giving this welfare state its particular structure.We relied on specific theoretical guidelines and concepts derived from the much honored holistic tradition in anthropology and political economy, as well as on formulations developed by scholars coming from the new tradition in the development approach in welfare studies.The analytical elucidation presented here indicates that a multiplicity of both internal and external factors and/or determinants have simultaneously influenced the development of the oil welfare state in Kuwait. The origins, nature, timing and interplay of all these factors appear to be specific and unique to the experience of Gulf societies, and have given rise to particular socio-political configurations and psychological effects. Thus the new soical welfare conditions which have emerged in modern Kuwait are different in many significant ways from those experienced in both the advanced industrial capitalist societies and Third World countries. Moreover, the economic, social, cultural and historical specificities of the oil-rich societies have made the overall development and the functions of the welfare state different from those found to be recurrent in advanced capitalist societies.It appears that, on one hand, the new oil welfare state has succeeded in modernizing life and bettering the human condition of its small population. Yet, on the other hand, this form of extensive oil-welfarism has in itself generated certain conditions which appear to have some-what weakened the capacities of these societies to achieve genuine development. In other words, it has failed to stimulate the development of productive social forces and other supportive infrastructural conditions from within society itself. A thorough analysis of these and other consequences which have become well embedded in the fabric of Kuwaiti society and culture requires and entirely separate paper.Sulayman Khalaf is Assistant Professor of Anthropology, Kuwait University.

The role of allelopathy in citrus replant problems was investigated in Iraq. The failure of citrus seedlings to grow normally in old citrus orchards was not caused by differences between old and non-citrus soils in electrical conductivity, pH, organic matter, soil texture and those minerals tested. Extracts of soil collected from old citrus orchards significantly reduced the growth of sour orange seedlings. Extracts and decaying sour orange roots reduced the growth of sour orange seedlings as did extracts of non-senescent sour orange leaves and decaying senescent leaves. Thus it appears that allelopathy is at least partly involved in the citrus replant problem. 相似文献

A double-stranded RNA unwinding and modifying activity was found to be present in a wide range of tissues and cell types. The level of activity did not vary significantly with respect to the state of cell differentiation, cell cycle, or transformation. Thus, the unwinding and modifying activity, localized in the nucleus in somatic cells and capable of converting many adenosine residues to inosine, appears to be one of the housekeeping genes. 相似文献

The effects of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), its metabolite 1-methyl-4-phenyl pyridinium ion (MPP+, cyperquat) and a structurally-related compound paraquat on mitochondrial functions were investigated in isolated organelles from rat striatum, cortex and liver. MPTP (0.1-1.0 mM) had no significant effect on various parameters of mitochondrial oxidative phosphorylation. In contrast, MPP+ (0.5 mM) inhibited the oxidation of the nicotinamide adenine dinucleotide (NAD+)-linked substrates pyruvate and malate but not that of the flavin adenine dinucleotide (FAD+)-linked substrate succinate. Paraquat (5.0 mM) significantly stimulated basal oxygen consumption (state 4) without influencing the oxygen utilization (state 3) associated with adenosine diphosphate (ADP) phosphorylation. Thus, these structurally-related compounds have different effects on mitochondrial oxidative phosphorylation, but the organelles from striatum, cortex and liver were affected in a similar manner by these compounds. 相似文献

Mini-exon derived RNA is a small nuclear RNA of trypanosomatid protozoa such asLeishmania which donates its 5′-terminal 39 nucleotides to the 5’-ends of cellular messenger RNAs by trans-splicing. We have cloned
a mini-exon derived RNA gene fromLeishmania donovani and studied its organization and expression. About 200 copies of the gene per haploid genome are organized as a tandem repeat
on a single chromosome. The gene is transcribed as a 95-nucleotide RNA. The first 39 nucleotides of mini-exon derived RNA
is also found at the 5′-terminus of a cellular mRNA (Β-tubulin), thus confirming its identity. Sequence analysis of the gene
and its flanking regions showed that while classical RNA polymerase II promoter elements such as TATA and CAAT are absent
from the 5′-upstream region, intragenic sequence motifs resembling RNA polymerase III promoter elements are present. The implications
of this finding for mini-exon derived RNA expression are discussed. 相似文献

Escherichia coli strains harboringtrans-acting mutations affecting the expression of Mn-superoxide dismutase (SOD) gene (sodA) were used to studysodA regulation. Complementation studies revealed that eitherarc (aerobic respiratory control) orfur (ferric uptake regulation) loci independently complemented anaerobic expression of asodA::lacZ protein fusion in one mutant strain (UV16). This mutant exhibited phenotypes (i.e., elevated outer membrane proteins, enzyme activity, and dye sensitivity) typical offur andarc mutants. When these mutations were introduced into an otherwise wild-type background, anaerobicsodA expression occurred only when botharc andfur mutations were present simultaneously, suggesting cooperative roles of Fur and Arc insodA repression. The reconstructedfur arcA andfur arcB double mutants were still inducible by iron chelators, suggesting the possible involvement of another iron-containing repressor protein. A second independent mutant strain harboring atrans-acting regulatory mutation (UV14) was only partially complemented by multicopy plasmids carryingfur
+ orarc
+ genes, implicating other genetic elements insodA regulation. 相似文献

A rabbit metallothionein-2 pseudogene (MT-2 psi) has been isolated from a partial rabbit genomic library. Its unusual sequence shows evidence of complex rearrangements involving recombination and deletion events. There are no intervening sequences, 3' poly A tract or 5' regulatory DNA sequences. The pseudogene is flanked by two sets of direct repeats (CT)3 GT(CT)4 and CTGG(G)CTC. They are most probably the sites of insertion of MT-2 psi in the rabbit genome. In addition, a number of repetitive DNA sequences are observed flanking the MT-2 psi gene. These are features of a processed retrogene. 相似文献

Molecular dynamics simulations and energy minimization studies of cyclic enkephalin analogues incorporating retro-inverso modifications have been carried out. The dynamic trajectories are analyzed in terms of the relative mobility of the 14-membered rings, conformational transitions among equilibrium states, and hydrogen-bonding patterns. The cyclization of the molecules reduces the motion of the ring structures substantially. Time-correlated conformational transitions resulting in the reorientation of peptide units are observed. Hydrogen bonds form principally C7 structures. Because of the incorporation of retro-inverso residues, C6 and C8 structures are also formed. Starting conformations for energy minimizations were obtained from the molecular dynamics simulations and from a systematic search of the conformational space available to the molecules. Several minimum energy backbone and side-chain conformations were found for each analogue. The effect of retro-inverso residues on hydrogen-bonding patterns and backbone conformations is discussed. 相似文献

Regulation of the manganese-containing superoxide dismutase is independent of the inducible DNA repair system in Escherichia coli 总被引:3,自引:0,他引:3
Studies on the induction of the manganese-containing superoxide dismutase in several strains of Escherichia coli with different mutations in recA and lexA revealed that the inductions of the Mn-isozyme and of the SOS system by oxygen free radicals are not coregulated. We also studied the synthesis of the manganese-superoxide dismutase in the temperature-dependent, protease-constitutive strain recA441(tif-1) that also contained a lac fusion in an SOS gene. A shift to the temperature at which recA441 has constitutive protease activity did not induce Mn-superoxide dismutase but did induce beta-galactosidase. The data clearly demonstrate that induction of the Mn-superoxide dismutase is independent of the SOS system. 相似文献
